Answer: x=9,-1
Step-by-step explanation:
First, we are gonna start out with finding two numbers that multiply to equal -9 and add up to equal -8
Those numbers would be -9 & 1
-9+1=-8
-9x1=-9
Now we have
(x-9)(x+1)
x-9=0 x+1=0
+9 +9 -1 -1
x=9 x=-1
X divided by 12 is less than or equal to 6
(y² - 3)(y⁴ - 6y² + 9)
y²(y⁴ - 6y² + 9) - 3(y⁴ - 6y² + 9)
y².y⁴ - y².6y² + y².9 -3.y⁴ - 3.(-6y²) -3.( 9)
y⁶ - 6y⁴ + 9y² - 3y⁴ + 18y² -27
y⁶ - 6y⁴- 3y⁴ + 9y² + 18y² - 27
y⁶ - 9y⁴ + 27y² - 27
I hope this helps.
